For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0046] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0047] This embodiment relates to a heat exchanger combination module, which includes a frame 1, a water-cooled condenser 2, a battery cooler 8 and an interface bracket 3 in terms of overall structure.

[0048] The water-cooled condenser 2 and the battery cooler 8 are fixed on the frame 1, and the interface bracket 3 is located above the water-cooled condenser 2 and the battery cooler 8 and fixed on the frame 1. Moreover, the refrigerant inlet and outlet pipelines and the coolant inlet and outlet pipelines of the water-cooled condenser 2 and the battery cooler 8 are both connected to the interface bracket 3, and a first coolant pump 12 is provided on the coolant inlet pipeline of the water-cooled condenser 2, and a second coolant pump 7 is provided on the coolant inlet pipeline of the battery cooler.

[0049] Based on the above overall structure, an exemplary structure of the heat exchanger combination module of this embodiment is combined Figures 1 to 6 As shown in , in which the solid lines with arrows on the pipelines in each figure represent the flow direction of the coolant, and the dotted lines with arrows represent the flow direction of the refrigerant.

[0050] As a preferred embodiment, the water-cooled condenser 2 and the battery cooler 8 of this embodiment are placed vertically on the frame 1, that is, the refrigerant inlet and outlet pipelines and the coolant inlet and outlet pipelines in the water-cooled condenser 2 and the battery cooler 8 are arranged up and down. Such an arrangement is not only conducive to the discharge of air when filling the coolant, but also has a better heat exchange effect.

[0051] It is understandable that, in addition to both the water-cooled condenser 2 and the battery cooler 8 being placed longitudinally on the frame 1 , only one of them may be placed longitudinally on the frame 1 , or both of them may be placed transversely on the frame 1 .

[0052] In addition, based on Figure 6 As shown in the state, as a feasible implementation, the coolant inlet of the water-cooled condenser 2 is located on the right side of its top, and the coolant outlet is located on the right side of its bottom, while the refrigerant inlet is located on the left side of its top, and the refrigerant outlet is located at the bottom of the other side of the water-cooled condenser 2 and is connected to the drying tank 10 or the gas-liquid separator described below. In addition, in order to take into account both the convenience of layout and the good heat exchange effect, as Figure 6 As shown in the figure, in this embodiment, a connecting pipe connected to the refrigerant inlet and outlet pipelines inside the water-cooled condenser 2 is provided on the outside of the water-cooled condenser 2, and the refrigerant inlet is formed at the top of the connecting pipe, thereby making the flow directions of the refrigerant and the coolant inside the water-cooled condenser 2 opposite, thereby improving the heat exchange effect.

[0053] Still by Figure 6 As shown in , the coolant inlet and outlet of the battery cooler 8 are located on the same side, and the coolant inlet is specifically located on the left side of its top, and the outlet is located on the right side of its bottom, while the refrigerant inlet and outlet are respectively located at the bottom of the other side. Moreover, in order to improve the heat exchange effect, the coolant and refrigerant in the battery cooler 8 flow in opposite directions, and its specific structure can refer to the prior art. For example, it can be as follows Figure 6 As shown in FIG. 8 , an auxiliary pipeline is provided outside the battery cooler 8 so as to realize the opposite flow directions of the coolant and the refrigerant inside the battery cooler 8 .

[0054] Depend on Figure 5 Combination Figure 6 As shown in FIG. 1 , in order to further improve the use effect, the water-cooled condenser 2 and the battery cooler 8 of this embodiment are arranged side by side on one side of the frame 1, that is, arranged side by side on the Figure 2 At the same time, the first coolant pump 12 and the second coolant pump 7 are arranged on the other side of the frame 1, and generally, the first coolant pump 12 and the second coolant pump 7 are centrifugal electronic pumps.

[0055] In this embodiment, in order to improve the use effect, the first coolant pump 12 and the second coolant pump 7 are respectively arranged relative to the outlets of the water-cooled condenser 2 and the battery cooler 8, that is, the inlets of the first coolant pump 12 and the second coolant pump 7 are respectively arranged relative to the outlets of the water-cooled condenser 2 and the battery cooler 8. Such an arrangement can not only effectively reduce the connecting pipelines between the first coolant pump 12 and the second coolant pump 7 and the water-cooled condenser 2 and the battery cooler 8, thereby reducing energy loss, but also help to reduce the flow resistance of the coolant, thereby obtaining a better heat exchange effect.

[0056] In addition, as a specific implementation method, Figure 1 and Figure 5 As shown in , a three-way valve 6 is connected to the outlet of the second coolant pump 7, one of the interfaces of the three-way valve 6 is connected to the second coolant pump 7, and the other two interfaces are connected to the coolant outlet pipeline leading to the above-mentioned interface bracket 3. Here, it should be noted that in addition to setting the three-way valve 6 at the outlet of the second coolant pump 7, the three-way valve 6 can also be set at the outlet of the first coolant pump 12 according to design requirements, and the three-way valve 6 can also be set at the outlets of the first coolant pump 12 and the second coolant pump 7. Moreover, in addition to setting the three-way valve 6 at the outlets of the first coolant pump 12 and the second coolant pump 7, a two-way valve can also be set depending on the specific situation.

[0057] In order to obtain better heat transfer effect, Figure 1 and Figure 4 As shown in , a drying tank 10 is connected to one side of the water-cooled condenser 2, and the outlet of the drying tank 10 is connected to the refrigerant liquid outlet pipeline leading to the interface bracket 3. In addition, in addition to connecting the drying tank 10 to the water-cooled condenser 2, the drying tank 10 can also be replaced by a gas-liquid separator according to specific circumstances. In order to further improve the use effect, an electronic expansion valve 9 is connected to one side of the battery cooler 8, and a refrigerant control valve 5 is provided on the refrigerant liquid outlet pipeline of the battery cooler 8, which can be specifically a stop valve. Among them, in a specific implementation, the inlet of the electronic expansion valve 9 is connected to the refrigerant liquid inlet pipeline leading to the interface bracket 3, and after the outlet is connected to the refrigerant control valve 5, it is connected to the refrigerant liquid outlet pipeline leading to the interface bracket 3.

[0058] It is worth mentioning that, in addition to installing the refrigerant control valve 5 on the refrigerant outlet pipeline of the battery cooler 8, the refrigerant control valve 5 may also be installed on the refrigerant outlet pipeline of the water-cooled condenser 2, or the refrigerant control valve 5 may be installed on the refrigerant outlet pipelines of both.

[0059] In this embodiment, in order to obtain a better heat exchange effect, a sensor component 11 is provided at the refrigerant outlet of the drying tank 10 to detect the refrigerant pressure and / or temperature. Based on the design requirements, the sensor component 11 can specifically adopt a pressure sensor, a temperature sensor, or a temperature-pressure integrated sensor. By providing a sensor, the first coolant pump 12 can be controlled based on the pressure and temperature parameters of the refrigerant, thereby adjusting the flow rate of the coolant to meet the heat exchange requirements.

[0060] In addition, it should be noted that, in addition to providing the sensor component 11 on the drying tank 10 , the sensor component 11 may also be provided at the electronic expansion valve 9 , or the sensor component 11 may be provided at both the drying tank 10 and the electronic expansion valve 9 .

[0061] Based on the arrangement relationship of the above components, the structure of the frame 1 of this embodiment is described in detail below. Figures 7 to 9 As shown in , the frame 1 is provided with a first mounting bracket and a second mounting bracket 15. The first mounting bracket is used to fix the water-cooled condenser 2 and the battery cooler 8 on the frame 1, and the second mounting bracket 15 is used to fix the first coolant pump 12 and the second coolant pump 7 on the frame 1.

[0062] As a feasible implementation method, the structure of the frame 1 of this embodiment is as follows: Fig.11 As shown in , the frame 1 is L-shaped as a whole and has a bottom plate 101 and a side plate 102, and the frame 1 can be made of 3-6 mm aluminum or 2.5-5 mm steel.

[0063] In addition, in order to reduce the vibration between the heat exchanger assembly module and the car, a shock-absorbing rubber pad 16 is embedded in each module mounting hole 1011, and a steel sleeve with a through hole is inserted in the shock-absorbing rubber pad 16. Moreover, the shock-absorbing rubber pad 16 is cylindrical as a whole, and a card slot for being clamped on the side plate 102 is formed on its outer circumference. At this time, in order to facilitate the embedding of the shock-absorbing rubber pad 16, a notch connected to each module mounting hole 1011 is opened on the side plate 102, so that the shock-absorbing rubber pad 16 can enter the module mounting hole 1011. In addition, in order to facilitate lightweight design, weight-reducing holes are opened on the side plate 102 and the bottom plate 101 of the frame 1.

Moreover, to facilitate installation and disassembly, the pipe openings of the coolant inlet and outlet pipelines located on the interface bracket 3 are connected with a quick-insert structure 4, and its specific structure can refer to the prior art. In addition, in order to improve the structural strength of the interface bracket 3, as shown in FIG. Fig. 9 As shown in FIG, a plurality of crisscross reinforcing ribs are provided on the inner side of the interface bracket 3 .

[0065] Still refer to Figure 7As shown in , the first mounting bracket of this embodiment includes a lower bracket 14 fixed on the bottom plate 101, and an upper bracket 13 fixed on the side plate 102. The aforementioned refrigerant control valve 5 is mounted on the upper bracket 13, and a control valve mounting seat 1301 is provided on the upper bracket 13. The aforementioned water-cooled condenser 2 and battery cooler 8 are both fixed between the upper bracket 13 and the lower bracket 14, and the drying tank 10 is fixed on the lower bracket 14. Among them, the structure of the upper bracket 13 is as shown in FIG. Fig.11 As shown in , a first mounting upper groove 1302 and a second mounting upper groove 1303 arranged adjacent to each other are formed thereon.

[0066] At the same time, Figure 7 As shown in FIG. 1 , a first lower mounting groove 1401 opposite to the first upper mounting groove 1302 and a second lower mounting groove 1402 opposite to the second upper mounting groove 1303 are formed on the lower bracket 14. In addition, in order to facilitate lightweight design, as shown in FIG. Fig. 9 As shown in , a weight-reducing groove is formed at the bottom of the lower bracket 14 for fixing the position of the drying tank 10. At this time, in order to improve the structural strength, a plurality of crisscross reinforcing ribs are constructed at the bottom of the lower bracket 14.

[0067] The upper and lower ends of the water-cooled condenser 2 of this embodiment are respectively embedded in the first upper mounting groove 1302 and the first lower mounting groove 1401, and the upper and lower ends of the battery cooler 8 are respectively embedded in the second upper mounting groove 1303 and the second lower mounting groove 1402. In addition, in order to avoid mutual influence between the water-cooled condenser 2 and the battery cooler 8, as shown in FIG. Figure 7 As shown in FIG. 1 , both the lower bracket 14 and the upper bracket 13 have a partition portion, which is used to separate the water-cooled condenser 2 from the battery cooler 8 , and the partition portion constitutes the side wall of each of the above-mentioned mounting grooves.

[0068] It should be mentioned that, in addition to providing the partition on both the lower bracket 14 and the upper bracket 13 , the partition may also be provided on only one of the lower bracket 14 or the upper bracket 13 .

[0069] Depend on Fig.12 Combination Figure 7 As shown in the figure, the second mounting bracket 15 of this embodiment is fixed on the bottom plate 101, and includes a base 1501 for connecting with the bottom plate 101, and a matching piece 1502 installed on the upper part of the base 1501. The matching piece 1502 includes two half rings formed in one piece, and two fixing holes are formed between the two half rings and the base 1501 to fix the first coolant pump 12 and the second coolant pump 7 respectively. As a specific implementation method, the matching piece 1502 is screwed to the base 1501.

[0070] Finally, it should be noted that the specific structures of the frame 1 and the first mounting bracket and the second mounting bracket 15 of this embodiment can be adjusted accordingly according to design requirements, and the first mounting bracket and the second mounting bracket 15 can be made of metal or plastic depending on the specific situation.
